Helium-mercury method can be used to determine the _____________ of the catalyst particle?
Correct answer: D. All A., B., & C.
- A. Pore volume
- B. Solid density
- C. Porosity
- D. All A., B., & C.
Explanation
Helium measures the volume of the solid framework because it penetrates accessible pores, while mercury determines the pore volume it cannot enter under the test conditions. These measurements can be used to calculate solid density, pore volume, and porosity.
